C1 1 Using Equations 2 3 And 5 And Any Two Lan Points From Table E1 4 Calculate Ko And Ra Of The Machine For 1 (39.29 KiB) Viewed 41 times

C1.1 Using equations (2), (3), and (5), and any two lan points from Table E1.4. calculate ko and Ra of the machine, for V₁ = 120V and I = 250 mA; for better accuracy, the two points should be the extremes, i.e., one from the top and the other from the bottom of the table. Show all the work. Report the results in Table C1.1, below. Then, compare this value of kop with the value of kø you found in P1. Calculate their difference as a percent of the latter, i.e., as a percent of the value of kø you found in P1. Table C1.1: R, and kø, for V = 120 V and I, = 250 mA. Ra(2) ko (Nm/A) E = ków (₂) Va = E + Rala (3) 19 = 1490 mA n=1114 rpm n = 955w (5) n = 1290rpm @ • 1a = 200mA
